CCD images

All these images are taken with the cpx3m camera prototype.

M3 V-band full field ; 360 seconds total exposure, LX200-12'' at f/7, through a photometric 'V' filter, bin 1x1. Images stacked and "curved" with the gcx program. Converted to jpeg with The Gimp. Image is at 1/2 resolution.

M3 V-band center ; Central portion of the previous frame at full resolution.

M3 I-band full field ; 460 seconds total exposure, LX-200-12'' at f/7, through a photometric 'I' filter, bin 1x1. Images stacked and "curved" with the gcx program. Converted to jpeg with The Gimp. Image is at 1/2 resolution.

M31 nucleus; Stack of 18 10-sec frames, 12'' at f/7. The image reaches Mag 19 despite the glow of the galaxy.

M31 south of the nucleus and M32; Stack of 25 10-sec frames, 12'' at f/7. I could identify at least one Cepheid (at mag 19.8) on this image; A follow-up image is certainly planned.

moon13s.jpg | moon3s.jpg These two pictures had exposure times of 0.04sec. A filter was used to reduce the brightness, and there were thin clouds, which helped avoid saturating the sensor; taken through the 12'' at f/10.

Wide-field M31 This image is taken through a 180/2.8 ED Nikkor lens (at f/4). Total exposure: 50mins. A larger version of the image is available here.

Horesehead Stack of 50 20-second images taken with the 12'' at f/7, using a red filter. The camera was tilted when taking this image - i ''solved'' the problem by only showing a lo-res image.

V838-Monocerotis Nova candidate showing expansion shell (picture taken on December 10, 2002), using the 12'' at f/6.3, x1 binning, stack of 39 20-second exposures.
